Scientists have reported that an experimental vaccine targeting one of the most common genetic drivers of pancreatic cancer, called mutant KRAS, is safe and generated a durable immune responses aimed at preventing the cancer.
Adults may not understand what an infant is feeling but it's child's play to another baby.
A paper in Infancy contends that infants can recognize each other's emotions by five months of age.
"Newborns can't verbalize to their mom or dad that they are hungry or tired, so the first way they communicate is through affect or emotion," says psychology professor Ross Flom of
Brigham Young University
. "Thus it is not surprising that in early development, infants learn to discriminate changes in affect."
Rat poison used for marijuana fields is killing fishers in the southern Sierra Nevada, according to a new paper.
Oxygen is necessary for survival on Earth but the planet's atmosphere did not always contain this life-sustaining substance. One of science's greatest mysteries is how and when oxygenic photosynthesis—the process responsible for producing oxygen on Earth through the splitting of water molecules—first began.
Geobiologists writing in PNAS say they have found evidence of a precursor photosystem involving manganese that predates cyanobacteria, the first group of organisms to release oxygen into the environment via photosynthesis.
All stars begin their lives in groups, though most, including our Sun, are born in small, benign groups that quickly fell apart. Others form in huge, dense swarms that survive for billions of years as stellar clusters.
Within such rich and dense clusters, stars jostle for room with thousands of neighbors while strong radiation and harsh stellar winds scour interstellar space, stripping planet-forming materials from nearby stars.
That's an unlikely place to find alien worlds.
Yet 3,000 light-years from Earth in the star cluster NGC 6811, astronomers have found two planets smaller than Neptune orbiting Sun-like stars.
Aaron Hernandez, until today a young, rich ($40 million contract) tight end for the New England Patriots football team, has been arrested and charged with the murder of Odin Lloyd, who had been dating his fiancée’s sister.
The key piece of evidence: Bubblicious bubble gum. Prosecutors say they can prove Hendandez purchased gum at a gas station hours before the murder and that they believe a chewed piece of gum found at a crime scene will have DNA from Hernandez, which would place him in the vehicle involved and thus as the murderer.
Researchers in the U.S., Europe and Japan have produced the first comparison of both the DNA sequences and which genes are active, or being transcribed, between the domestic tomato and its wild cousins.The results give insight into the genetic changes involved in domestication and may help with future efforts to breed new traits into tomato or other crops, said Julin Maloof, professor of plant biology in the College of Biological Sciences at the University of California, Davis and senior author of the study in PNAS.
If you can scorch a baseball over the mound, you can thank extinct ancestors.That's not to say that, despite what an evolutionary psychologist might contend, our ability to throw fast and accurately evolved so our ancestors could play ball better and therefore get more dates.Instead, this ability first evolved nearly 2 million years ago - humans are unique in our throwing ability - to aid in hunting.
Claims from Chen-Yu Zhang's group at China's Nanjing University made international headlines when they reported that, after mice ate lettuce, bits of genetic material from the plants made its way into their bloodstreams intact - and could turn the animals' own genes off.Miracle vegetable of the week journalists said it was a triumph for the promise of medicinal food. Scare journalism of the week writers instead worried that genetically modified food might modify consumers in unanticipated ways.Look for actual science to receive far less attention.
A computer analysis of nearly 2 million Tweets on the Twitter online social network revealed another divide in the religious culture war - while atheists engage in more analytical thinking, Christians use more positive words and fewer negative words.To identify Christian and atheist Twitter users, the researchers studied the tweets of more than 16,000 followers of a few prominent Christian and atheist personalities on Twitter. They analyzed the tweets for their emotional content (the use of more positive or negative words), the frequency of words (such as "friend" and "brother") that are related to social processes, and the frequency of their use of words (such as "because" and "think") that are associated with an analytical thinking style.
Despite, the hype, and though the Apple iPad® is being used for intraoperative procedure guidance, percutaneous procedure planning and mobile interpretation of some imaging examinations - rather limited benefit - the majority of radiology residents are using it instead as a really expensive way to read journals, according to a paper in the Journal of the American College of Radiology.
A total of 38 radiology residents in the radiology program at Beth Israel Deaconess Medical Center in Boston were provided with iPad 2 tablets and subscriptions to e-Anatomy and STATdx. After six months of device use, residents were surveyed to assess their opinions regarding the technology as a tool for education and clinical practice.
During the last American presidential election, the Obama team highlighted that support for their victory was across the board - 8 of the 10 wealthiest counties in America had gone their way, which was meant to show that rich people believed in his vision also.
That means 8 of 10 counties feel something must be done about climate change, but if an analysis of Swiss homes is similar to America, they mean someone else must do the changing.
Writing in Environmental Science&Technology, Dominik Saner and colleagues found that energy conservation in a small number of households could go a long way to reducing greenhouse gas emissions.
We constantly grow new skin and shed the old but no one is sure exactly how it works. New research says they may provide the answer.
Engineers and biologists at the University of Sheffield say a recent hypothesis - that skin has 'sleeping' stem cells which can be woken up when required - best explains how our skin constantly regrows. The research, conducted by The Procter&Gamble Company (P&G), makers of Olay, and the University of Sheffield and published in Nature Scientific Reports, may have implications for combating the effects of aging.
